suddenly increased in velocity, and at 2 a.m. the record shows a speed of sixty 

 miles per lionr. I'nfortunitely shortly after 2 o'clock, the clock-work which 

 keeps the registering portion of the appivatns in motion was stopped, the motion 

 of the pemliilum being undoubtedly arrested by a sudden blast of great violence. 

 This stoppage was not dircovered until 3 o'clock a.m., so that between the.so 

 liours the record is lost. At 3 o'clock the instrument was put in motion again 

 and for about fifteen or twenty minutes after that hour, the record shows the 

 extraordinary velocity of ninety-five miles per hour. From this time the violence 

 diminished rapidly, a velocity of fifty miles per hour being registered at 4 a.m., 

 and at 5 a.m. it had fallen to less than twenty miles per hour. Twice afterwards 

 as will be seen by the chart, the speed rose to about twenty-five miles per hour, 

 after which it rapidly declined. 



Owing to the intermption in the continuity of these records, it is impossible 

 to affirm that the maximum velocity of the wind was recorded. In fact there 

 are reasons for believing that the storm rc.ached its greatest violence somewhat 

 before 3 o'clock. 



It seems quite certain then, that at times during the storm tlie velocity of 

 the wind exceeded one himdre 1 miles per liour; and especially must this havo 

 been the c.".se during some of the most violent blasts which were generally of too 

 short duration to show with their full effect upon the register made. The fact 

 that the pendulum of the anemograph was stopped between 2 o'clock and 3 

 o'clock by one of these blasts, and that after 3 o'clock its motion was not inter- 

 fered with, would indicate that more violent disturbances took place before than 

 after that hour. A smaller anemometer of Eobiiison's model was torn from its 

 fastenings between 2 o'clock and 3 o'clock, and so completely demolished that no 

 record even of the work which it had already done couhl be obtained. This is 

 much to be regretted, as otherwise a means of verifying the extraordinary velo- 

 city reijistori'd by the anemograph would h:ivo existed. Concerning the latter it 

 should b? sail that, regavding the smaller anemometer as a standard, it has been 

 foimd upon examination to somewhat over-estimate the velocity of very liigh 

 winds, and to nnder-estimate tlioso of low speed. At the same time it cannot 

 bo positively stated which of the two instruments was in error. 



A continuous record of th" direction of tiie wind is ki'pt. Upon examining 

 this it is found that during the whole of the period considered, the direction 

 varied between Js'orth and West. I'p to 1 o'clock a. m. of the 4lh the wind wn.s 

 slealily from the North-north-west. From that hour until ä o'clock a. m. its 

 fluctuations were confined between North west and West. A decided change in 

 direction Beoms to liavo taken jilace l)etwecn the houis of 2 o'clock and 3 o'clock. 



The early |>art of the stonn was accompanied by an unnsuilly Ir'avy fall of
